I had the most wonderful surprise yesterday when the postman delivered 5 cover flats for RAMPANT! I've only ever had cover flats from one publisher - Black Lace. I'd forgotten that Harlequin sent them out to, and it was a real treat to see it for real.
The scan doesn't quite do it justice, but you can click on the image to get a larger version. The back and front cover are matt with gloss on the lettering, and the spine is all glossy.
